EUVD-2024-35298

Comprehensive Technical Analysis of EUVD-2024-35298

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in Diño Physics School Assistant version 2.3 involves an improper authorization issue within the file /classes/Users.php?f=save. The manipulation of the id argument can lead to unauthorized access, potentially allowing attackers to perform actions they should not be permitted to.

Severity Evaluation:

• Base Score: 9.8 (Critical)
• Base Score Version: CVSS 3.1
• Base Score Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

The CVSS score of 9.8 indicates a critical vulnerability. The vector string highlights the following:

• Attack Vector (AV): Network (N)
• Attack Complexity (AC): Low (L)
• Privileges Required (PR): None (N)
• User Interaction (UI): None (N)
• Scope (S): Unchanged (U)
• Confidentiality (C): High (H)
• Integrity (I): High (H)
• Availability (A): High (H)

This vulnerability can be exploited remotely without any special privileges or user interaction, making it highly dangerous.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Insecure Direct Object References (IDOR): An attacker can manipulate the id parameter in the URL to access or modify data they should not have permission to.
• SQL Injection: If the id parameter is not properly sanitized, it could be used to inject malicious SQL code.
• Cross-Site Scripting (XSS): If the id parameter is reflected back to the user without proper sanitization, it could be used to inject malicious scripts.

Exploitation Methods:

• Manipulating URL Parameters: An attacker can change the id value in the URL to access different user accounts or perform unauthorized actions.
• Automated Scripts: Attackers can use automated scripts to iterate through possible id values, attempting to access or modify sensitive data.

3. Affected Systems and Software Versions

Affected Software:

• Diño Physics School Assistant version 2.3

Affected Systems:

• Any system running the vulnerable version of Diño Physics School Assistant.
• Systems that have not applied the necessary patches or updates.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Apply the latest security patches provided by the vendor.
• Access Controls: Implement strict access controls and validation for the id parameter.
• Input Sanitization: Ensure all input parameters are properly sanitized and validated.
• Monitoring: Increase monitoring for suspicious activities related to the /classes/Users.php?f=save endpoint.

Long-Term Strategies:

• Code Review: Conduct a thorough code review to identify and fix similar vulnerabilities.
